County officials issued seven violations to Dickey’s Barbecue in South Jordan following a January inspection, Salt Lake County Health Department records show. The year before, the restaurant had six violations.

Authorities say a worker at the establishment unintentionally put a chemical cleaning compound in a sugar bag last month. The substance ended up in a Sandy woman’s glass of iced tea Aug. 10 after an employee mixed it into a beverage dispenser.

In January, the restaurant was cited for two critical violations: employee beverages being too close to food prep areas and a dirty can opener, records show. Mislabelling of food is considered noncritical and is a common violation, health agency spokesman Nicholas Rupp said.

Overall, this Dickey’s has maintained a better-than-average health rating since opening, he said.

In February 2013, the citations against the restaurant included incorrectly storing foods that can spoil; an employee not washing hands before putting on gloves; and a dirty ice machine.

Health officials visited the restaurant Aug. 11, the day after Jan Harding unknowingly drank the tea, and found a bag of sugar was not labelled. Rupp said the restaurant threw out all the sugar in the establishment after the incident but neglected to label one of the new containers with sugar.

The Salt Lake Tribune first reported the health violations.

Harding remains hospitalized but was upgraded from critical to serious condition this week. The 67-year-old can now talk with some effort and is breathing on her own, family attorney Paxton Guyton said.

Doctors last week determined she suffered deep, ulcerated burns in her upper esophagus and burns to her mouth.

The cleaning product in the tea was meant for degreasing deep fryers and contained the odourless chemical lye, the active ingredient in drain cleaners.
